Solid Oral Dosage Forms
Beyond-Use Date (BUD) Prediction
Explainable estimation of the beyond-use date for tablets, capsules, and powders based on the API’s molecular descriptors, formulation characteristics (excipients, assay), environmental parameters (temperature, humidity), and packaging, leveraging published stability data.
What is this module for?
Scientifically justify the beyond-use date (BUD) for solid preparations; optimize the formulation by quantifying the impact of excipients and storage conditions; document decisions with an exportable report (PDF/CSV) and a ranking of influential factors.
Inputs
Dosage form characteristics and % API (assay); key excipients and formulation variables (e.g., moisture, viscosity where applicable); packaging (material, barrier) and environmental parameters (temperature, humidity).
Outputs
Predicted beyond-use date (BUD) with a confidence interval; analysis of influential factors (formulation, packaging, environment); exportable report for traceability and pharmaceutical justification.
Worked examples
Standard parameters (known formulation, controlled temperature) → direct BUD prediction.
Specific constraints (high humidity, critical excipient) → analysis of influential factors.
Assessing the impact of changing material/barrier on beyond-use date.
Limits & precautions
Applicability domain constrained by available stability data; extreme conditions or outside the training space → increased uncertainty requiring experimental confirmation.
FAQ
Can the model predict if a parameter is missing?
How should I interpret a wide confidence interval?
This interactive tool is an experimental prototype developed in KNIME and provided solely for demonstration and training purposes. The results displayed (predicted Beyond-Use Date, influential factors analysis, etc.) are indicative and are not validated for clinical or regulatory use. They do not replace stability studies, official standards (Ph. Eur., USP, ICH), nor the internal procedures of any healthcare institution. The data must not be used as the sole basis for determining an actual Beyond-Use Date. Any interpretation must be carried out under the responsibility of a qualified pharmacist.
